Any discussion of "my insurance is high, who should I switch to?" is pointless. There are too many things that impact the insurance rates. The vehicle being insured, the coverage being requested (liability limits and comprehensive/collision deductible), the driver's record (tickets, etc...), the driver's credit score, the primary address the vehicle is stored at, if the vehicle is garaged, mileage per year (some policies are available with low-mileage coverage), the insurance company.
If you believe that your insurance premium is too high, you need to do some legwork and contact a few insurance agents to get actual quotes for you and your vehicles. Any guidance you receive on this thread for where to find discounted insurance is next to worthless.
Edit, my insurance premium on EVs is right in line with what I pay for gasoline-powered vehicles.
